cups cupsys - arbitrary code execution

It was discovered that the imagetops filter in cups, the Common UNIX
Printing System, is prone to an integer overflow when reading malicious
TIFF images.

For the oldstable distribution (etch), this problem has been fixed in
version 1.2.7-4etch7.

For the stable distribution (lenny), this problem has been fixed in
version 1.3.8-1lenny5.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem will be fixed soon.

We recommend that you upgrade your cups packages.
